What are the five most significant pieces of evidence that connected Arthur Lee Allen being the Zodiac Killer?

Answer 1

One of the most compelling 'coincidenses' occured at least a year before the first murders in northern California. Two friends of Allen's had a conversation with him where he described murdering people and using the name Zodiac. The murders were word for word accurate to what he told his friends.

He was seen on more than one occasion with cyphers and cryptograms almost identical to the ones that the Zodiac sent to police and newspapers, a year before the Vallejo killings.

Allen fit the physical description perfectly, down to the 'lumbering' way he had of walking, almost with a slight limp. Allen had surgery at one time leaving him with a very slight, odd hitch in his walk.

At one of the crime scenes a bootprint was left by someone wearing a military-issued boot called a WingWalker. These boots were only available to servicemen and their families in the western United States. Allen's father was a career military man and the family shopped at the local PX.

Everywhere Allen happened to be, whether at a job or working toward his many degrees, people ended up dead. When he went to southern CA there were Zodiac type murders, in Santa Rosa while attending Sonoma State at least 8 young women hitchhickers went missing, all suspected to have been killed by the same suspect. This occured everywhere Allen had been.

Allen was big on The Most Dangerous Animal, a book he read in high school about a man that hunts humans, because man is the most dangerous animal of all. Allen was really hung up on this book. He mentioned this book to almost anyone who knew him for more than 10 minutes.

The FBI criminal profile described a person that fit Allen almost exactly. At the times when no letters arrived to newpapers and police, Allen was either in prison or in the mental hospital. As soon as he was released, letters began to arrive again.

Allen's family, especially his brother and sister-in-law were certain he was the Zodiac. They cooperated with law enforcement and were intensely worried when an arrest was not made.

Allen's cars matched vehicles seen by witnesses. They were either his own cars, or cars of friends that he had access to, including cars driven to Los Angeles that were seen at the time and place of murders.

These are only a few of the facts that point the finger at Leigh Allen. In fact, police were preparing to get warrents and make an arrest at the time of Allen's death. We owe Robert Graysmith our gratitude for his investigation that lasted three decades and at least two marriages. He sacraficed much so the truth could be told.
